Sodalite is a fascinating mineral from the feldspathoid group, most often associated with a rich, deep blue color, though it can also be found in gray, yellow, green, or pink hues. Its name comes from its high sodium content.
A characteristic feature of sodalite is the presence of white or light-gray veins and spots of calcite, which create unique patterns on each specimen. This natural beauty makes sodalite a popular choice for mineral collectors, jewelry designers, and artisans creating decorative objects. It is often used for making cabochons, beads, figurines, and inlays.
Sodalite is valued for its aesthetic appeal and the uniqueness of each stone, highlighting its natural origin.
